Check out mc13224 based motes. http://www.redwirellc.com/store/ Their $55 econotag has an integrated USB based JTAG programmer - no need for an external one. 8 ADC channels that can sample at 10Khz Software is here: http://mc1322x.devl.org/ > > Robert > > > Quoting Miklos Maroti <[email protected]>: > >> Hi Robert, >> >> What sampling rate do you want to achieve? >> >> Miklos >> >> On Thu, Apr 8, 2010 at 8:37 PM, Robert F.
